Operation
Turn the
sag setting wheel
clockwise to
increase the spring pre-tensioning.
Turn the
sag setting wheel
anti-clockwise to
decrease the spring pre-tensioning.
You will have made the ideal setting if the
shock absorber deflects 3 mm when bearing
the rider's weight.
3
Replace the plastic cover on the crown
after
making the setting.
6.6.5.2 Adjusting the Suntour fork air
suspension
Only applies to pedelecs with this equipment
The
air valve
is located beneath the
air valve
cap
on the
crown. Twist off the
air valve cap
.
Figure 41: Screw caps in different designs
1
Attach a high-pressure damper pump to the
air
valve
.
2
Pump air suspension fork to the required
pressure. Observe the levels in the Suntour
filling pressure table. Never exceed the
recommended maximum air pressure
.
3
Detach high-pressure damper pump.
4
Measure the distance between the crown and
the dust seal. This distance is
total deflection
of
the fork.
5
Push a temporarily attached cable tie
downward against the dust seal.
6
Put on your normal cycling clothing, including
luggage.
7
Sit on the pedelec in your usual riding position
and support yourself against an object, such as
a wall or tree.
8
Get off the pedelec without allowing it to
deflect.
9
Measure distance between the dust seal and
the cable tie.
This measurement is the sag. The
recommended value is between 15% (hard)
and 30% (soft) of the total fork deflection.
10
Increase or reduce air pressure until you have
reached the desired sag.
11
If the sag is correct, turn the
air valve cap
clockwise.
12
If you are unable to achieve the required sag,
an internal adjustment may be needed.
